SHADE-ADJUSTER.

Application filed April 24,

the art to which it .appertains to make and use the same.

Th1s invent1on elates to shade adjusters, and it relates more specifically to an improved vertically adjustable window-shade supporting and guiding device.

One object of this invention is to generally improve upon devices of this character,

' side of the'shade adjuster in elevation, the

em ofFig. 1.:

- being in horizontal section;

and especially to. improve, simplify and cheapen'the device disclosed in my Patent No. 1,249,936, dated December 11, 1917 these improvements comprising such angular adjustability that enablesthe device to work easily and quietly under adverse conditions where other devices of this character are unsatisfactory.

Other objects and advantages may become apparent to persons who read the following details of description in connection with the accompanying drawings, in which':-

appropriate construction, and the elements 23, 24, '25, 26 and 27 being the same as the similarly designated elements of my prior patent:

Thls device comprises a shade support or bar 28, a guide 29, a track 30 and other elements which willhereinafter be mentioned and descriped. The shade support 28 has the usual shade bearings 31 and 32 secured at its opposite ends, and the inner side of the bar 28 is provided with extensions or flanges which extend horizontally past the tracks sides which face towardon'e another, so as to prevent movement of the shade support outwardly with relation to the window frame. These extensions 33 may be in the form of sheet metal plates which are securedto the ma n portion of the support 28fby means of screws, as lndicated in the drawings,.and the shade brackets or bearings 81and 32 may be secured? on these plates or extensions by any appropriate Imeans or formed integrally therewith.

Referringnow to Figs. 2, 3 and't, it will seen that the bar or shade support 28 has an extension 34 which overlaps the outer t ion, asi'ndicated at 36.- At opposite sides of 'the bulge 36 the member. 35 is. formed with apertured ears 37, and screws 38 extend throughthese ears into screw-threaded engagement with the guide 29. By referring to Fig. 2,'it will "be seen that the holes through which the screws 38 extend are ;sufiiciently large to permit angular adjustment of the 'elements 29 and 35 with relationto one another, and the screws;38 are operatable to effect such angular adjustment by first looseningone screw, then tightening the other. This angular adjustment of the elements 29 and 35 is an important fea ture of this 1nvention,'.as it permits this device to be, quickly,i easily, and properly 'apphed to w ndow frames which are out of plumb, thatis, to window frames in whichthe upright sides lean toward or from the center of the window, as is often the case because of inaccuracy in buildingor because of the uneven settling of a wall in which the window is supported. In this connection, it should be understood that it is desirable andimportant that the. axis of that my shade support 28 shall be practically horizontal at all times, regardless of the inclination of the'window frame sides from the vertical, it is important that the guide 29 be held substantially in a fixed angularity with relation to the window frame, and that the angularity of the shade support be, adjusted accordingly; and therefore, the guide 29 is. held substantially in parallel relation with the track 30 by means of a flange 39.01: this track, saidflange extending outwardly of the window frame and being spaced from'the window frames surface to c which it is attached. In the space between the flange 39 and opposing surface of the window frame a lower roller and upper rollers 11 arefjournaled on the guide or bar 29; and in practice, the

a roller 40 rolls on the contiguous surface of the' flange 39 while the rollers 41' roll on j the contiguous surface of the window frame 7; This is true because the raisingand lowering means 23 is connected to the shade support in such position that the 'end of the shade support which carries the guide 29 slightly overbalances the other end of 'the' shade support, thereby pressing the roll ers 41 against the window frame while pressing the roller 40 against the flange of the 'track; The purpose oftwo rollers 4E].

"ing on a comparatively smooth or plain surface;

is to enable this guide to ride over nailholes, [knot holes, and other depressions which often exist in new as well as old window "frames. It will be seen that while one ofthe rollers 41 is opposite to one of such depressionsand tends to enter same, theother of said rollers is likely to be rid- As an auxiliary to the flanges or exten- --sions 33, the guide 29 may be provided with an arm or angularretaining member 42 which extends outward from the guide 29, thence towardthe middleof the window frame, thenceinward of the'windowr frame and thence away from the center of the window frame, thereby passing from the "outerr'to the inner side of the track 30 and "cooperating therewith and with'the asso- ::ciated flange 33 for holding the rollers 10 andal in the space between the flange 39 and window frame. j

Although there are two of the tracks30 and they "are :of counterpart construction,

as disclosed herein, the left-hand track 30 v in Fig. 1 may be of a different construction,

' but it is importantthat theright-handtrack V 2. In a shade supporting and guiding device, a substantially horizontally extending tentof said shade-support;

30 be substantially of the construction illustrated in Fig. '2, that is, it should be substantially L-shaped, being preferably formed integrally of wood and provided with apertures through the larger one of its flanges for receiving nails and for securing it to the window frame. This provides a substantially noiseless track which can be formed at a comparatively slight expense with a wood working machine for such purposes and can be out in suitable lengths, with an ordinary saw or knife, for fitting windows of different heights. 7

Although I have described this embodiment of my invention very specifically, it is not intended to limit this invention to these exact details of construction and ar ,rangement of parts, but changes may be made within the scope of the inventive idea, as specified and claimed. V What I claim as my invention is 1; In a shade supporting and guiding device, the combination of substantially horizontally extendingshade-supporting means, track-engaging means on one end of the shade-supporting means, and means toelfect angular adjustment of said track-engaging meanswith relation to the horizontal extent of. said shade supporting means.

shade-support adapted to be attached to a window having an upright track, a guide adapted to travel along said track and be held thereby substantially in a fixed angularity relative thereto, and means to secure said guide to said shadesupport, said means" being operable to, efl'ect angular adjustment of said guide relative to the horizontal ex- 3. In a shade. supporting and guiding device, a shade-support adapted to be attached to a window having an upright track, a guide adapted to travel along said track and be held thereby substantially in a fixed angularity relative thereto, said shade-support comprising a bulged surface and two apertured ears, these ears extending respectlvely upward and downward from the bulge of said surface, and screws'extending' through said apertured ears and en gaging with said guide and holding the latter against said bulged surface, said screws .being operat'able to effect angular adjustment of said guide relative tosaid shadesupport. 7 5 r 4. In a shade supporting and guiding attachment for a window frame, a track secured in an upright position on the-window frame and comprising a flange that'extends outwardly of and in parallel and spaced relation to the window frame, a substantially horizontally extending shade-support, a bar secured to one, end of the shade-support and extending downward therefrom,

means to adjust said bar angularly with relation to the horizontal extent of said shadesupport, rollers on the upper and lower ends of said bar" and disposed in the space between said flange and the adjacent part of the window frame, and an angular retaining member on said bar and extending across the side of the said track opposite to said flange and being efiective to retain the rollers in said space.

5. In combination, a shadesupport, a guiding track vertically disposed at one end of the shade-support and comprising a flange, a guiding bar carried by said end of the shade support, a roller journaled on the lower end portion of the guiding bar in a position to roll along on said flange, a plurality of rollers journaled on the upper end portion of said guiding bar in a position to roll on the window frame, and means to raise and lower said shade-support, said means being so connected to the shade-support that the end which carries said guiding bar and rollers slightly overbalances the other end of the shade-support.

In testimony whereof I have hereunto set my hand.
